Went to check on my car today again. I have some unknown ratio of antifreeze and water. Last week it got down to -10C/14F and nothing burst so I guess there's at least 20% antifreeze in there, right?
Still starts like **** but the battery is a champ! Just cranks and cranks and cranks and cranks.

I've had nothing but horrible luck getting my **** started that cold on E85. To be honest i go back to gasoline in the winter just for that reason. I cannot get my car started at less than 8-10F even on gasoline. Not sure what the problem is.
I'd start with the timing advance per water temp map, then to the fuel enrichment map per water temp. I'm running a .029 spark on stock coils which is what i'm pointing my finger at.

Perhaps this can somehow be translated to Megasquirt: E85 Cold Start Issues addressed. - Subaru Impreza WRX STI Forums: IWSTI.com
Are you running AEM? (never mind, your sig says ms3/3x)

Add more fuel. For a certain temperature and MAP a certain percentage of the fuel evaporates when the injector shoots. Only the evaporated fuel ignites. If you were to find the values graphed for both normal gas and e85 you'd see how little E evaporates at these low temps. You need to throw a whole dickload of e85 into the car to generate enough e85 vapor in the combo chambers to get combustion.

Adding a boat load of fuel is the way to go

18psi, I wonder if it is due to the design of the Forester's boxer engine and the long runners.

The foz, like my wrx does have the injector maybe an inch further from the valve which could help, the runners also look a whole heck of a lot bigger. The combo chamber is also probably better shaped, the air all moving around in the combo chamber certainly helps the atomization.

Yeah, my definition of "cold starting" is being able to start the car every 1-2 weeks in Winter just to warm it up and keep all the fluids going.
Thats all.
Anyways, I got a Skunk2 throttle body. By mistake I bought the 94-97 version and had to contact Skunk2 support directly to get the 99-05 parts (really just a plate and gaskets to mount the idle valve)

I wonder if it's all in the priming pulse/cranking enrichment. You don't want to fuel outside of starting.
I think the wear on the motor starting it every two weeks is significantly higher than the wear just parking it for the winter and starting it at the end. Why put yourself through that?
If you're so worried, mail me turbo and manifold and I'll keep them whetted during these 72 degree weeks.

They have some cold start settings which may help, i.e. simultaneous injection rather than sequential on cranking. a cranking enrichment taper which allows you to give a massive shot of initial fuel but then quickly taper away.
Apologies if I'm teaching you to suck eggs.
